Sony DTC670 DAT Recorder No Sound and it is chewing my tape

[@andypalm7061]

I just like these units. (when working) lolI have a few 75es's to enjoy while we can keep them working. They are a challenge .

Done this recap to the exact same model a few years ago. It really is a plague :/ But now works like new :) Also, the plastic from the remote control desintegrated into pieces along with the eaten traces from battery leak, had to glue it all together, enforce with some epoxy on the inside, sand it and respray and also resolder bunch of traces but works after all :)

Good morning 🌞 Dave you are very top notch at fixing electronics 💯💯💯🙏🏽🙏🏽

Glad I sold my DAT Walkmans which were working fine but for how long.

[@12voltvids]

The walkman models had many mechanical problems like plastic gears that stripped.

You are Amazing!!! Love your vids! 💙💙💙

[@jefftobin4034]

It impressive to see you sleuth these complex systems. I'm curious why you don't use surface mount caps as replacements, especially when there are space limitations.

[@12voltvids]

Local shops dont sell them thats why and i dont order anything online. Shipping too expensive.

[@jodydavid3753]

How can I contact you. I need you to repair a video Deck

Preamp caps on Sony DAT machines are always bad. Think they used the cheapest ones they could get back then.

[@12voltvids]

They were all defective. Panasonic made them.

If you had a needle syringe it would be easier to put oil, I have some with diff kind of stuff when cleaning/oiling small parts. Just a tip. ;-)

Its amazing how Sony completely locked down their consumer products to near uselessness just to please their own in-house record label (many of their MP3 players included with atrac/sonicstage), but then slaps a "for professional use" on rather mundane consumer looking gear that allows recording anything. DAT never stood a chance in consumer use. EDIT: its cool though how they used a rotary head drum on such a small width tape format. Also curious if sony knew about this bad cap problem by the time they produced this machine, opting only to place the shoddy ones on the pre-amp board is odd, as the entire mainboard uses normal through-hole caps.

[@12voltvids]

I see you are into conspiracy theories. Ok. Serial copy management was mandated by the us government and Supreme Court when the iraa (international recirding artists association) and recird companies lobbied and pressured them. For consumer cd recorders they had the same limitations and even required special much more expensive blank discs. Dat didn't stand a chance because philips introduced their dcc format which confused the market and nobody bought on to either from a consumer format. The recording industry on the other hand adopted Dat and did not need copy protection enabled. You can turn it on or off on professional decks. Same with professional cd recorders. They use regular computer cdr and cdrw discs. As to caps nobody knew they were going to fail. They were all defective in manufacture. The bad caps were all made by panasonic.

[@spikester]

@@12voltvids How is that conspiracy? Sony played a direct role in lobbying for those rules, whom the RIAA represents. Sony not only built the consumer products but were also one of the largest major record labels of that era. Its no secret they regularly crippled their consumer products due to needing corporate approval with their record label/sony pictures assets.

Go back and read all the rulings. Sony had virtually no involvement in recording back then. They had a minor interest in CBS records. The manufactures fought the implementation of copy protection for years. DAT would have been on the market in the early 80s, it actually predates the compact disc but was tied up in the courts. Do you remember the betamax court cases when Disney and others tried to block the betamax and they lost. Had they won you would never had a vcr because that case was about prohibiting recording on TV. Nobody wanted a locked down recorder. Sony fought hard to get the scms 1 copy ruling. The record companies wanted zero copies period. They could not market any machines until the court decided. So the way it ended up was 1 digital copy. That digital copy can not be digitally coped again. You could make as many digital copies from cd as you want. You could also also make the master using analog input and make digital dubs of that first gen tape. You could copy it 100 times if you wish. The second gen copy could not be copied however. So the limits really didn't do anything. Dat failed for consumer use not because of the limitations but because of market confusion due to the DCC cassette with its promise to play analog tapes. Many were waiting to see which format would succeed and then came along recordable cd and minidisk. That spelled the end of tape formats.

[@spikester]

@@12voltvids Makes sense, Sony got into music around the same time DAT was released to the public which was where I associated it. I didn't know there were originally 2 DAT formats proposed, one with rotary head and another stationary. Had the latter existed in the late 80s with cheaper compact cassette compatible players it might had succeeded, DCC which used stationary heads came out way too late in the 90's which wasn't much longer the CDR's & minidisc finished off tape as you said.

[@12voltvids]

They were held up for years with the legal battle and then dcc just caused confusion. People still remembered vhs vs beta. Dcc was a garbage format. High compression but it took years to make it work. Never lived up to the hype. Meanwhile dat had established itself in the professional market and many consumers bought into the pro machines as did pretty much every musician that was setting up a home studio. Many brought the alese adat 8 track and mixed to dat. Then the da88 was released. You could stack multiple machines for 24 or 32 tracks. You could also stack multiple da40 decks and radio stations automated with them for years until hard drive playback took over. Dat had a good run for 25 years.
